it captures prey on its tentacles it is brought to its body by contracting its tentacles in a corkscrew motion. It feeds on plankton which includes organisms such as mollusks‚ crustaceans‚ tunicate larvae‚ rotifers‚ young polychaetes‚ protozoans‚ diatoms‚ eggs‚ fish eggs‚ and other small organisms. All Aurelia including the Moon Jellyfish swim by pulsations of the bell-shaped upper part of the animal. Swimming mostly functions to keep the animal near the surface of the water rather than to make

Study Guide 4 CH. 21 Genomics – the study of whole sets of genes and their interactions. Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

Oxides Research 1. Assess evidence‚ which indicates increases in atmospheric concentration of oxides of sulfur and nitrogen. Thorough collection of data‚ surveys‚ and tests from the 1950’s indicate a rising trend in atmospheric concentrations of oxides of sulfur and nitrogen. An enhancement in funding‚ technological and information resources‚ has led to wider and more detailed analyses of oxides of sulfur and nitrogen concentrations‚ and as the diagrams indicate (see diagrams) there is a clear

TITLE By: Brittany Bolling April‚ 28th 2011 Dr. Woolnough BIO 101 DO6A ABSTRACT: The objective of this study was to observe and understand what occurs in a sample of pond water over the course of six weeks. Over the six weeks there were qualitative and quantitative data found and recorded. The qualitative data recorded entailed: Water color and smell as well as suspended solids ranging from clear‚ opaque‚ and turbid. The quantitative data that was recorded regarded: Temperature‚ pH‚ Alkalinity

Algae are simple organisms that typically produce their own food through photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very

upper part of lakes there is a good supply of light‚ heat‚ oxygen‚ and nutrients‚ well distributed by currents and turbulence. As a result‚ a large number of diverse aquatic organisms can be found there. The most abundant forms are plankton (chiefly diatoms)‚ algae‚ and flagellates. In the lower levels and in the sediments‚ the main forms of life are bacteria. See also limnology. Heavy Water Water from most natural sources contains about 0.015% deuterium oxide; this can
